AirProbe is the air quality application developed for EveryAware, a project whose aim is to let citizens measure and be aware of air quality around them, through the combined use of a sensor box and this application, installed on an Android phone. The sensor box records the concentration of pollutants in the […]
One of the objectives of the “Every Aware” project is monitoring some environmental variables of the surrounding environment, such as temperature, relative humidity and some air pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), volatile organic compounds (VOC) and ozone (O3).
For this purpose we developed a dedicated “sensor box” based on an Arduino chipset, that, […]
A time-domain recognition of different wireless technologies may be obtained using energy detection. In this work, an energy detector was implemented using the Universal Software Radio Peripheral SDR platform. The energy detector output allows the formation of a packet presence/absence diagram. Experimental results indicate that the observation of Bluetooth packet exchange patterns reveals technology-specific MAC […]
